SPECIFICATION forming part of Letters Patent No. 536,425, dated March 26, 1895. Application filed February 16, 1895. Serial No. 538,602. (No model.)

To all whom it may concern- Be it known'that I, LOUIS HACHENBERG, a citizen of the United States of America, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Cable-Grips, of which the followingis a specification.

My invention has reference to a cable-grip for cables running in underground conduits and has for its object to provide means whereby the cable can be quickly lifted and gripped by the use of a single operating lever with little or no injury to the cable itself with continued use.

To this end my invention consists essentially in the combination with a grip-body, of hinged wings having a link connection with the shank, a lifting sheave mounted on one of said wings, two wedging surfaces located in the grip-body on opposite sides of the grip-shank, an operating lever, intermediate connections between said lever and the grip-shank for reciprocating the same, and springs acting on the wings for spreading the same on the depression of the grip-shank.

The nature of my said invention will best be understood when described in connection with the accompanying drawings,in which- Figure 1 represents a sideelevation of a cable car provided with my improved grip. Fig. 2 is a side elevation of the grip drawn on an enlarged scale. Fig. 3 is a sectional end elevation. the line 4-4, Fig. 2. Fig 5 is a bottom view of Fig. 2. Fig. 6 represents the two wings of the grip in detail. Fig. 7 is a sectional side elevation, part being broken away. Fig. 8 is side elevation showing the grip-shank partially depressed. Fig. 9 is a vertical section on the line 9-9, Fig. 8. Fig. 10 is a bottom view of Fig. 9.

Similar letters of reference designate corresponding parts thoughout the several views of the drawings.

Referring now to the drawings, the letter A designates the grip-body suspended from the frame of the truck B in any suitable manner. Within said body is mounted, and guided to reciprocate vertically, the grip-shank O, the upper end of which is engaged by bell crank levers a a pivoted to framesbattached to the grip-body. The bell crank levers a a are vi- Fig. 4 is a vertical section on brated by means of eitherof the operating levers D D (Fig. 1) located on the opposite platforms of the car, as usual, and to which they are connected by links 0 c.

E E designate two wings pivoted to swing about a common shaft (1. The ends of the wings are provided with upwardly projecting arms e which are connected by linksf to the lower end of the grip-shank O. The wings, when brought together, fit snugly in the bifurcated, or yoke-shape, end of the grip-body (Figs. 3 and 4), and, in addition thereto, are held together by flat springs g 9 located in vertical grooves in the grip-body and bearing upon the backs of said wings. The Wings are, furthermore, acted on by two spiral springs h h attached to the ends of the shaft 01 and to the grip-shank. In the wing E isv mounted a lifting sheave S, the pintle of which is adapted to enter a bearing 2' in the opposite wing E when the two wings are broughttogether.

Within the bifurcated end of the grip-body A are mounted two wedging surfaces S S located respectively on opposite sides of the grip-shank O and in the plane of the lifting sheave S when the latter is in its operative position. In the present example I have shown the wedging surfaces in the form of rotatable sheaves, butI do not Wish'to restrict myself to the use of the same. The general object of the present construction is to lift the cable B when the car is to be started and to wedge it between the lifting sheave S and the wedging sheaves S S; while at other times the parts are above the cable, and the car can pass over cross cables without interterference.

The operation of the grip is as follows: Assuming the parts to be in the position shown in Figs. 8 and 9 and that it is desired to start the car, the lever D is thrown over in the proper direction to lift the grip-shank 0, thereby drawing the wings E E together and upwardly by means of the link connection f and the arms-e e. The lifting sheave S engages with and lifts the cable, drawing it up firmly between the two wedging sheaves S S, and it is held in this position by a usual pawl and segmentj in connection with the operating lever. To release the grip the operating lever is turned in the opposite direction causing the grip-shank to belowered and freeing the wings from the grip-body (Fig. 9). On the downward movement of the wings the free ends of the flat springs g 9 leave the body of the wings and engage with and press upon the arms 6 6 thereof, thereby turning said wings about their shaft d to open the same. Simultaneously therewith the spiral springs, h, acting on the shaft d, assist in.

opening the wings to release the cable and then hold the same open.

W'hat I claim as new is-- p 1. A grip for cable cars comprisingin its structure a grip-body,1a; reciprocating gripshank moving vertically within said body,-

hinged wings in connection with said shank, alifting sheave mounted on one of said wings, two wedgin g surfaces on the grip-body-loeated on opposite sides of the gripshan-k, springs adapted to act on said wings for opening the same, and meansfor operating the grip-shank, substantially as described.

2. A grip for cable cars comprising in :its structure a grip-body, a reciprocating gripshank moving vertically within said body,

hinged wings provided with upwardly :pro-i jecting arms, links connecting arms with the grip-shank, a liftingsheave mounted on.

one of said wings, two wedging sheaves on the grip-body located on opposite sides of the shank, springs adapted to act on said wings for opening the same, and means for op-- erating the grip-shank, substantially as described.

3. A grip for cable cars comprising in its structure a grip-body, a reciprocating gripshank moving vertically Within said body, hinged wings provided with upwardly projecting arm's,'links connecting said arms with the grip-shank, a lifting sheave mounted on oneof said wings, two weclging surfaces on the grip-body located on opposite sides of the shank, flat springs secured in the body and actingou the wings to open the same, spiral In testimony that I claim the foregoing as my invention I have signed my name in the ,presence ot the two'subscribing witnesses.
